Doors up to 2400mm high can be operated by hand without the need of chain wheel equipment

Doors between 2400mm and 3000mm use efficient direct chain drive

Doors over 3000mm high use efficient, compact, planetary reduction gearing

Quiet and durable nylon gearing

Ease of single handed operation

Gearing components require no lubrication due to materials used in manufacturing

Balanced loading and withstands very high overload forces without ill effects

Mullions can be simply disengaged to provide unrestricted full width access

Mullions for smaller doors lift out by hand

Individual low effort operation

Privacy and weather protection of a small opening

Wicket Gates

Wicket gates provide quick and easy access in or out of the premises, without the need to raise the door. Features include:

Opening size is 1780mm high x 600mm wide. This gate is specified when inward opening is required

Fitted with external key operated night latch lock

When the door is in the open position the cranked bottom rail hangs 65mm below the lintel

Our wind-locking technology incorporates a unique clip design fitted to the edge of every flat on our high wind rolling doors. When exposed to high wind situations, this clip design ensures the door is held captive in the door track, it reduces the risk of both blow-in and blow-out wind forces, and provides added protection against forced entry

In any area that could be affected by high wind or extreme weather conditions, B&D recommend the fitting of Windlock Guide Systems

Complies with the high wind requirements stated in the National Construction Code*.

*The B&D Roll-A-Door® S2 roller door has have been tested in accordance to the wind requirements of AS/NZS 4505:2012 (Garage Doors & Other large Acess Doors) which complies to AS/NZS 1170.2:2011 (Wind actions) and AS 4055:2012 (Wind loads for housing)

The NT Deemed to Comply Manual (DTCM) is referenced in the Building Code of Australia, Volume 2, Part 3.10.1 as an acceptable construction manual for high wind areas.

The Manual contains products or systems which have been assessed for structural adequacy for cyclonic wind loads and approved by the NT Building Advisory Committee (BAC). These drawings can be accepted by architects, builders, building certifiers, designers, engineers etc as complying with the structural requirements of the NT Building Act.B&D’s DTCM drawings can be downloaded via the DTCM website or by clicking here.
